Advanced Simulation and Empirical Validation of High-Efficiency Induction Heating System Via COMSOL Multiphysics

Induction heating is recognized for its high efficiency and rapid heating performance, making it an essential advancement in various applications. Its capacity for precise heat control results in considerable energy conservation and supports sustainability in different industrial and domestic applications. This paper presents the simulation design and empirical validation of a high-efficiency induction heating system. The initial phase involves simulating the induction heating system using COMSOL Multiphysics, producing results such as coil inductance, coil effective resistance, and estimated steady-state heating efficiency and distribution. A 1KW power converter prototype is constructed and evaluated, with the output voltage and current waveforms measured. The system's regulation is managed through two distinct algorithms implemented with a DSP 28379D microcontroller. The results show a close alignment between the simulated and the practical system, emphasizing the simulation model's accuracy.
